Unable to receive external emails


My site had been down for sometime and i changed ISP's and moved to dsl from cable, and now my email won't work.
I can receive all mails sent to the root by the system, but if i try sending an emai to an external email like gmail it just queue's them up and when i look at the queue it says network not found as the reason for not sending. When i send mail from gmail to my email it keeps trying to send until it tells me permanent failure in sending to my eamil. I have tried teleneting to mysite.com 25 to see if everything is ok from other comps on the network and everything seems to be ok. I will try this from another comp ouside my network but in the meantime can anyone run a test and see if they will get a response from the smtp on my site. My site is www.muthii.com.
Any help on how i can trouble shoot will be highly appreciated i use Postfix.

I don't seem to ge ta response from port 25, but can ping that address. IP I see is 68.219.52.196

You need to guve more info on setup.

Have you forwarder port 25 on your router, is your firewall open, does yo ISP allow port 25 traffic?

If you check your site with dig for a MX record there isn't one. This is the most likely problem. You need to complete your MX record so that it points to your IP address. As billymayday has suggested you also need to forward requests on port 25 to the mail server if you are using a router.

Rechecked my mx settings everything is ok. But my isp isn't allowing traffic on port 25. Thanks all for your help. Need to look into switching isp's.

Ask them if they'll unblock incoming port 25 requests, and you can relay through their smtp server for outgoing traffic

Did they accommodate you, or did you switch?

They said i have to upgrade my service and get a static IP with no blocked ports. Being a student i have to keep to my budget so am giving it a pass for now.

Who is this ISP?

Also, is there any chance that there is a port like 2025 that they have left open as an alternate, but the tech you spoke wasn't aware of it?

That's not going to help him with MX records and receiving emails. It's not like an apache webpage where you can specify the port in the address. The standard is 25 for MTA's.

I'd recommend editdns.net ; if you are intent on running your own mail server, you can setup a free account with them. A quote from their "features" page:


Free MX Re-Routing (With optional spam filtering)
Does your ISP block port 25 and you want to run your own mail server? We will automatically re-route all your email to a non-standard port.

Furthermore -
Free DNS Hosting
Easy, web-based interface for adding/modifying/deleting records for your domain name. We support A, CNAME, MX, NS, SRV, TXT, PTR, and AAAA records.
Free Dynamic DNS
Do you have a dynamic IP from your cable or DSL company? You can automatically update your IP address for your domain as soon as it changes.

With those 3 features and a knowledge of how to configure NAT/port forwarding on your router, you'll be receiving Viagra related emails in no time.

Another alternative would be to have your own Linux Box, in the form of a Virtual Private Server (VPS), this will run $10-$20 per month. Still, a 3rd option would be to host a machine at a data center. It's not cost prohibitive if you go with the right company, I use one called Colopronto.com and a 1U rack with 500GB of transfer costs me about the same price as a dialup account - $24.95


Sorry for the blatant mentioning of 3 companies, but since there's no technical way to do the solution on your own, it was necessary.
Disclaimer: I am a customer of all three of the companies listed, get a small percentage knocked off my bill for referrals, and don't care if that happens or not.

Hopefully one of these solutions will work for you. Best of luck.
